CA1 Considerations

"Although there are various reports that are supported by TMS (CA-1), DLMSCR expects Report-05 or Report-06 or Report-87 to be used.

The report generation parameters should request the field DSN17 instead of the default DSN. Otherwise, the report for multivolume multifile tapes has the incorrect DSN for all but the first VOLSER. Those volumes with incorrect DSN fail the DSN validity check that is performed by DLMSCR before scratching a tape."
